D3 Tool Steel Supplier UK
D3 (1.2080) is an oil hardening, high carbon, high chromium cold work tool steel, like D2 but with a slightly higher hardness. It displays excellent abrasion/wear resistance with high compressive strength and hardens with very little change in its dimensions. It is heat treatable but should not be overheated as it will not achieve maximum hardness if heated improperly.
Whilst D3 is a great all-round tool steel, the metallurgy of tool steels is complex, so if you need any help determining the best steel for a given application, please get in touch with details of your intended usage. There may well be a new specially developed next generation tool steel that will perform even better for your required application.
